Hi All

I am trying to find out what the chain guard looked like on a 1914 2 speed.

I have a 1913 to 1923 parts list but the guard for 1914 is not shown nor even listed, part 1806D "Stud securing cahin guard to engine 1913-19 is listed suggesting there was a chain guard that extended from in front of the front sprocket to the gearbox as a part 651D Chain guard stay (two-speed) 1913-19 is also listed but no Chain Guard.

Did my machine even have one as the position for the stud on the crank case has never been drilled and tapped.

Any information would be helpfull

regards Chris

Chris, are you wanting a close-up picture of a 1914 2 3/4 with a chainguard? I'll pop up to the shed with a camera.

Yes please, cheers

This one is 1913 - hopefully the same.

And another

And from the front.

Hi,
    Just to add a little confusion, some of the 2¾'s had a cast boss on the crankcase just under the front barrel, and a cast/forged bronze lug on the chainguard as a front fixing. In which case, the bracket onto the rear crankcase stud would be omitted.
  Regards,
              Eddie.

Hi Chris
Not very original but an easy way to replicate these chain guards is to make them from plastic. Take a length of 25mm electricians black plastic conduit. Using a bending spring and warming the plastic tube in boiling water the correct radii to suit the front and rear sprockets can be formed the correct distance apart. Mark out the sides of the tube on the halfway mark then carefully cut along this line with a hacksaw. file up the edges and shape each end nicely. Indistinguishable from original in appearance and will not rust. can be polished or painted. Alternatively you can use copper pipe for greater rigidity but more difficult to cut neatly and has to be painted. Chris.

Thank you all for the pictures comments and suggestions, as the crank case has not been drilled and tapped i will make a guard with bracket that attaches to the rear upper crankcase bolt.

Thanks to you all, Chris
